I found in modern engines the recommended dose of either MMO or TC-W3 is a bit much and as too heavy a dose milage drops . So I started playing around with ratios in my Kia / Hyundai 4 & 6 cylinder engines and found a recipe of : MMO @ 960 : 1 and TC-W3 @ 1920 : 1 ratios mixed together . At these levels I did NOT lose any MPG so it tells me that the dose was not too much (your milage may vary and it is possible you can mix stronger for your engine application) . Here is a web site where you can plug in the above ratios based on your gas tank size : http://www.csgnetwork.com/oilfuelcalc.html I'd be curious to see what others have to say about their results are using the above as a base starting point ? Goal was to lube & clean entire fuel system including useage as a UCL . * For reference : MMO recommended dose is 320 : 1 and the LC1 forum recommends TC-W3 at a ratio of 640 : 1 to gas .
MMO + TC-W3

Looks like you have to buy the Javascript program on line to use the calculator.
Recommended dosages are pretty light.
Yours are about one third of that. I wonder what benefits you are getting?

I'm still trying to figure that out - recommended doses really did a number on my gas mileage , so I dropped it back to where gas mileage jumped back up again . I may incrementally begin to add slightly - sweet spot for my modern engines looks like it will rest between a 1/2 and a 1/3rd of recommended dose .
I use 3 ozs. of MMO per 10 gal. of fuel. Seems to be my sweet spot.
remember hes not just dosing mmo or tc-w3, hes running them together, so the dosing isn't so light when you look at it this way.

Yep.....same here....I use a generic dosing though.....typically anywhere from 2.5 - 3 oz....no I'm not gonna grab the Bill Nye gear, graduated cyclinders, beaskers, and safety goggles out to the pumps
So I keep the MMO in a 2.5 oz. bottle of 2 Cycle Oil that came with one of my trimmers as a "sample"
That rate works great for my typical 9-11 gallon "fill".....I realize the bottle states 2.5 oz....BUT, I fill the bottle to the tip top.....so it's likely more like 2.75 oz But yea......it only takes a little fine layer of lube to keep the innerds lubed.

Too many things can happen, including gas pumps being out of wack, to show a little increase or decrease here or there.
However, for a few years every couple of tanks I have been placing 2 fl.oz. of MMO and 2 fl.oz. of TCW3 into a old bottle that is marked in oz and putting that into a full tank of gas.
I don't know how much it has been doing. But I have 180,000 miles on my Taurus, 108,000 on my F-150 and 75,000 miles on my Xterra and the fuel systems seem to be working fine.
I worry about cheap gas, you can never be sure of how trustworthy their marketing is.
I figure that a little bit of the additives that I add will help dissolve crud and keep things a little bit cleaner over the long run. If it helps as an upper cylinder lube, all the better.

My main concern is fuel pump lubing with alcohol infused fuels.
anything else is a nice perk.

All of my vehicles have 20 gallon tanks. I run a 50:50 mix of MMO/TCW3. I mix them in an old quart of Stabil bottle. I usually run 6 or 7 oz with an empty tank.

As you note, 2 stroke oil is a better lube. But no doubt MMO is a good lube, though.

Because the actual recommended ratio of MMO to gas is lower (320:1) than TC-W3 (640:1) - what ever ratio I end up with will be close to 2/3rds MMO to 1/3rd TC-W3 . I will also mention that MMO is more tolerant of over dose in an engine than TC-W3 (not very tolerant of over dose at all) .
Very true....lol. I overdid the TCW-3 once, and yep.....I felt it the minute I left the gas station parking lot.....I pretty much just babied the car that week, until half a tank, then topped off to "thin it out" - and didn't add anything that next fill.
Could even a slight TCW-3 overdose throw a CEL??
Perhaps indirectly.
I get CELs all the time when I use top-end foam cleaning. Only during the expel, though. Clears itself...

I don't know.....the couple times I used TCW-3....though it is "ashless" it just seemed a lot "thicker" than say, MMO.....which is likely WHY it's only advised to use 1 oz. to 5 gallons of TCW-3....whereas, MMO is typically 4 oz. to 10 gallons.
Havent had a "fuel system cleaner" related CEL in a long time though
hehe. Llast I had was with my 08 Kia.....driving home from work, I stopped at the gas station and dropped in a bottle of Seafoam.....well, on the way home I got the CEL.......BUT, the next morning heading to work, the "italian tuneup" as I merged onto the highway, "cleared the code" Cause it flickered, then disappeared....
Or my bulb just died (but unlikely on a 2 year old car hehe).
